Product Description
Sharpen fractional separations without the mess or hold-up of loose packing. Glass indentations along the inside of a Vigreux column create extra surface where vapor and condensate can exchange heat, improving separation of close-boiling liquids while the column stays easy to clean and reuse.
This listing is for Kimble catalog number 286710-0300: KONTES Vigreux Distillation Column, 19/22, 300 mm. Each column is made from borosilicate glass 3.3 with a standard taper outer joint at the top and an inner joint at the bottom, so it fits between a flask and a distillation head. Choose 14/20 at 130 mm, 19/22 at 300 mm, or 24/40 at 150, 300 or 600 mm to match the scale and separation your work requires. LIGHT LABS ships genuine DWK Life Sciences products with knowledgeable support from our Englewood, Colorado team.
